... alone, co-incubated with Caco-2 cells, or in rat jejunum segments. In E. coli , the addition of [γ- 32 P]ATP led to the uptake and subsequent hydrolysis of ATPe. Exposure to peptides caused an acute 3-fold (MST7) and 7-fold (MEL) increase in [ATPe]. In OMVs, ATPase activity increased linearly with [ATPe...

... unstimulated Caco-2 cells (15.1 pmol/mg), but other components did not change before and after the stimulation by PMA. Spectrophotometric analysis found approx. 36 pmol of FAD and 43 pmol of haem per mg of membrane and the turnover of superoxide generation in a cell-free system consisting of the membrane...

... in ABCA1 mass secondary to LXR activation. Inhibiting acyl-CoA:cholesterol acyltransferase activity prevented the decrease in cholesterol efflux caused by oleic acid. Thus, in response to LXR activation, all fatty acids decreased the efflux of cholesterol from the basolateral membrane of CaCo-2 cells...

... human epithelial cells, Caco-2, which express high levels of cell-surface ADA. Interestingly, the adhesion of Jurkat and CEM T cells to a monolayer of Caco-2 cells was greatly dependent on CD26. An increase by 50% in the cell-to-cell adhesion was found in cells containing higher levels of CD26...
